OIL AND CHIP PAN.

Application filed December 3, 1927.

This invention relates to oil and chip receiving pans for metal working machines, such as lathes and single and multiple spindle automatic screw machines, an object of the invention being to provide an improved pan of this kind so constructed as to give increased chip capacity while permitting a more effecive and expeditious cleaning out thereof.

A further object of the invention is the provision of an improved pan of this kind so constructed that the accumulated chips may be cleaned out at either side or either end.

In metal working machines it is usual to provide a pan under the bed of the machine for catching chips from the work and oil supplied in streams to the tools, and these pans quickly become filled with accumulated oil soaked chips, it being necessary to separate the oil from the chips in order to reuse the oil. Usually these pans are of shallow form which is necessary because otherwise it would be side thereof.

In the drawings accompanying and forming part of this specification, Fig. 1 is a side perspective view of this improved pan; Fig. 2 is an end perspective view thereof; Fig. 3 is a sectional view taken through the length of the pan; Fig. 4 is a part end and cross sectional view of the pan; Fig. 5 is a cross sectional view taken on line 5-5, Fig. 3; and Fig. 6 is a cross sectional view taken on line 66, Fig. 3.

Similar characters of reference indicate corresponding parts in the several views.

Before explaining in detail the present im provement and mode of operation thereof, we desire to have it understood that the in vention is not limited to the details of construction and arrangement of parts which are illustrated in the accompanying drawings, since the invention is capable of other embodiments, and that the phraseology which Serial No. 237,374.

we employ is for the purpose of description and not of limitation.

This improved pan preferably comprises a single casting usually installed under the bed of the machine in such position that it will receive the oil and chips from the work. This pan comprises a bottom 2, having upright side walls 8 and end walls 4 outwardly flared at their upper edges. The side walls are connected with spaced or bridging cross members or ribs 5 and 6 for the reception of the bed of the machine. Each end wall of the pan is cut away or recessed as at 7 to provide an enlarged opening thereby facilitating access to the pan at the ends. The side walls are likewise similarly recessed or cut away for the same purpose as at 8 from which inclined aprons 9 lead toward the center of the pan. By forming these cut-away portions or openat the ends and'sides the side and end walls can be of increased height and serve as protective guards for the oil as Well as give increased capacity to the pan. Supported at each end-in a sloping or inclined manner is a bottom plate 10, this plate being suitably and detachably supported by projections or lips 11 and 12. Each of these bottom plates is provided with two sets of perforations 13 and 14 one set adjacent to each end of the plate for the passage of the oil, so that the perforated bottom plates will effectively drain the oil into the large reservoirs therebelow from which it is usually drawn by suitable mechanism provided for the purpose so that it can be again reused.

From the foregoing it will be seen that the pan has sloping side Walls usually formed integral with the pan and perforated and inclined detachable end plates whereby the quick and easy cleaning of the accumulated chips is facilitated through either the ends orthe sides of the pan at either end or either side of the machine.

It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

Having thus explained the nature of our said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, We claim:

1. A chip and oil receiving pan comprising a casting having a bottom and upstanding side and end walls outwardly flared, said walls being formed to provide enlarged openings, said pan having inclined aprons adjacent to each of said openings, those adjacent to the side openings being integral with the pan, and those adjacent to the end openings being detachable from the pan.

2. An oil and chip receiving pan comprising a casting having a bottom and upstanding high side and end walls, the side walls having openings midway of their lengths and the end walls also having openings to facilitate access to the pan, the side walls having inclined aprons adjacent to their openings and the pan having inclined end bottom plates.

3. An oil and chip receiving pan comprising a single casting havin a bottom and upstanding end and side wills, said side walls connected by bridging ribs and having between said ribs a pair of enlarged openings for facilitating access to the pan and provided with sloping aprons to the interior of the pan, and said end walls also having enlarged openings to facilitate access to the pan, and detachable perforated oil draining plates located in an inclined position relatively to the end openings of the pan.

4. An oil and chip receiving pan comprising a single casting having a bottom and upstanding end and side walls flaring outwardly, said side walls connected by bridging ribs and having between said ribs a pair of enlarged openings, for facilitating access to the pan and provided with sloping aprons to the interior of the pan, and said end walls also having enlarged openings to facilitate access to the pan, and detachable perforated oil draining plates located in an inclined position relatively to the end openings of the pan.

5. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide portion of each wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof.

6. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide portion of each wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof, the side walls having bridging ribs connecting the same for supporting the bed of the machine.

7. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide central portion of each side wall having its upper edge at a lower level than the top edges of the .pan to provide accessible passageways to the pan below the top thereof, and such lower level having inclined aprons leading toward the center of the pan.

8. An oil and chip receiving pan compris ing a bottom and relatively deep side and end walls, a relatively wide central portion of each end wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof, and such lower level hav ing removable inclined aprons leading toward the center of the pan.

9. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide central portion of each side wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan be- -low the top thereof, the wall portions reaching to the top of the pan being outwardly flared.

10. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide central portion of each end wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof, the wall portions reaching to the top of the pan being outwardly flared.

11. An oil and chip receiving pan comprising a bottom and relatively deep side and end walls, a relatively wide portion of each wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof, the wall portions reaching to the top of the pan being outwardly flared, and said pan having inclined aprons adjacent to the walls having the lower level.

12. An oil and chip receiving pan comprising a casting having a bottom and relatively deep side and end walls, a relatively wide portion of each wall having its upper edge at a lower level than the top edges of the pan to provide accessible passageways to the pan below the top thereof, the wall portions reaching to the top of the pan being relatively high and outwardly flared thereby acting as a protecting medium against the splashing of the oil, whereby the pan will have increased capacity while substantially coinciding with the width and length of the bed pf the machine adapted to be supported there- )y.
